Application filed July 5,

My invention belongs to that general class of devices known as conveying apparatus, and relates particularly to an improved target and targetplate construction arranged at the discharge end of the system. The invention has among its objects the production of a device ofthe kind described that is simple, durable, eflieient and satisfactory for use wherever found applicable. More particularly it has as an object the producti on of a durable device of the kind described which will efliciently control the discharging of the material. Many otherobjects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given. 7 To this end my invention consists in the novel construction, arrangement and combination of parts hereinshown and described, and more particularly pointed out in the claims.

In'the rhrawings, wherein like reference characters indicate like or corresponding parts: I I

Fig. 1 is a view in elevation of my improved apparatus arranged in a storage tank shown in section.

Fig. 3 is a sectional view through the tar get plate; and

Fig. t is a sectional view through the coupling at the juncture of thedischarge pipe and fitting.

Referring to the drawings in which the preferred embodiment of the invention is shown, 1 represents aconveying system pipe which is extended as at 2, and provided with a fitting 3 at the inside of the tank, 4 being a replaceable wearback forming a part of the fitting. 5 represents any suitable box, tank or receptacle'of suitable size, shape and material, which may be provided with a cover or top 6 of suitable construction and a vent p pe 8. The tank provides a chamber 7 into which ashes or other material may be diseh rged and collected as necessary. The fitting is provided with a flange 9 which carrles a frame 10 connected thereto by the rods 11 or the equivalent. The frame part 10 is pro? vided with a renewable plate 12 termed a target plate, which I generally prefer to make with ribs 18 so as to form a series of pockets. 14. Material discharged from the fitting is directed against the target plate 12, which arrests its velocity and allows it to fall into Fig. 2 is a sectional View through the drain 1924.

the tank of its own weight and without packing the tank. The material generally fills up the pocketsl in which. the material solidly packs and forms substantially a target of.

the material discharged, which builds up as fast as it is worn away by the continual discharge against it. The construction and ar' rangement of the target is such that the same is in the line of the direction of travel of the material, and as the material'is discharged, it tends to fill the bin substantially evenly. In

other words, the material is not thrown en tirely to one side or the other, nor to more or less one point from'which it either must be shoveled back or reduce the capacity of the bin, but the same tends to be thrown ordeflocted more or less evenly about the bin.

Tllhe fitting 3 may be secured to the pipe 2 in any suitable manner, a simple construc- I tion con'iprising a flange 16 on the pipe 2 and a spl t lli'lf 19 arranged to engage a flange 18 on the fitting, the parts being secured together by bolts 17 or equivalent means for the purpose. Generally, I prefer to provide a drain pipe22. As shown, a drain fitting 2O isarranged between the pipes land 2, the

partsbeing secured together by bolts or their equivalent This fitting is formed with a dis charge opening 21 at the bottom, and ar ranged for attachment to the pipe 2 by means of a coupling23 or equivalent means for the purpose. 1

It will be noted that the drain fitting 20 is slightly tapered so thatthe pipe 2 and fitting 3 are slightly inclined upwardly from the fitting so that any water or liquid in the line will drain back and bedischarged through the pipe 22;

As before mentioned, the fitting consists of the part 3and wearback 4. The wearback 4 is removable so that it may be removed as required for inspection or replacement. A novel connecting means for securin the wearback in place consists of'lugs 25 and 26 on the parts, through which may be passed the ends of the U-bolt 27, if desired. A lug 28 may be provided on the" wearback for engagement with the U-bolt 27, in which case the lugs 26 may be omitted.

The construction illustrated has'many ad vantages. It will be noted that in the construction shown the material conveyed is discharged in an upward direction and allowed to strike at right angles against a plate, whereby it entirely loses its discharge Velocity and falls freely and evenly into the tank without packing, making the subsequent discharge from the tank easy. In a pneumatic or jet-conveying system the material con-- turned off all the material will drop by grav ity clear of the end of the discharge ipe. This is desirable as there is no dropping ack into the pipe of the material at the discharge.

end'which might obstruct the system when it tributes the material throughout the tank so that it fills up evenly from the bottom toward the top. The parts may be easily removed for V inspection or replacement. For example, the

' discharged down into target plate 12 may be lifted out at any time for inspection and replaced or renewed, if necessary, without requiring any bolting or fastening means. the weight of the same being sufiicient to hold it in place. The material, filling up the pockets li provides a face which will take the wear and which is being continuously built. up if any of it wears or breaks loose. The weal-back 4 may be re moved for inspection or replaced with case, may the entire fitting be disconnected from the pipe 2. Liquid and water accumulating in the fitting and pocketing therein may flow back into the drainfitti'ng 20 and thence be and out through the pipe 22.

Havingthus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from'the spirit of my invention;

hence I do not wish to be understood as limiting myself to the exact, form, construction,

arrangement and combination of parts herein shown and describedor uses mentioned.

lVhat I claim as new and desire to secure by Letters Patent is: i

1. In a conveying apparatus of the kind described and in combination, a discharge fitting arranged with the. outlet directed upwardly at an angle to the vertical and a target arranged in and transversely tothe path of the material discharged from ,said'outlet but spaced therefrom. i

2. In a eonveyin apparatus of the kind described and in com ination, a conveying pipe provided with a discharge outlet and arranged to discharge in an u ward direction i at an angle to the vertical, an a target spaced from the outlet and arranged in the path of the material discharged therefrom, said target consisting of aframe and means for supporting the same on said conveying pipe, an a target plate seated in said frame.
